CANNING- MAGIIINE.

Application led IOctober 9, 1925. Seri-a1 No. 61,481..

yThis invention relates to canningmachines, and is particularly directed to a packer attachment for such machines. i

In canning machines adapted to handle vegetables :and place them in cans, it is the usual practice to remove the cans from 'the canner and, thereafter, fill them with brine or other solution. When it is fattempted to apply the brine to the filled cans in the canner,it has been found that the brine flows into the cans land when removed `from the canner wash-es the vegetables out fof the cans.

This invention is designed to `.provide a packer attachment lior canning machines which will pack the vegetables into the cans in avery rapid fand (effective manner, Vand which may be applied to the ordinary canningmachines `with la .minimum Iof change.

Further objects are to provide :a paclcer for a canning machine which will pack the vegetables into the "can :and permit the fsubsequent filling of the cans with brine or other solutions without danger of washing the vegetables' rom fthe cans.

An embodiment of the invention is .shown l crank pin 1s connected by means :of ya pitman in the accompanying drawings, whichz-r Figure '1 4is 4'apla-nivfiew `of fa canning machine wiith the packer .in position.

Figure .2 is :a side elevation partly broken away of the structure shown Figure 1..

Figure y3 is #an enlarged sectional view :on the .line 3 3 of Figure 2, showing in detail the y'constru'cti'on of the plunger.

Figure 4 is ia rear view of 'the `structure shown `in Figure l. l

- Figures f5, S6 :and 7 :are i diagrammatic `views showing successive positions of 'the plunger and the can `upon which .it is to operate.

Reiterrin'g -to the drawings, it will be seen that the usual #type of canning [machine `has been illustrated in which the cans :are 1fed by lmeans :o- 'the ycurved rotor l beneath the feeding' ring Y2, sudh ring passing gbeneath the :member 8 which receives the lower :end of the vegetable chopper..

it `is to be noted that the drum -1 `is provided with the usual worm tooth 4 which engages :a :single can :at fa Vtime and places it beneath4 the ring 2 inthe usual manner.

This drum is driven by means of a pulley -5 controlled by a clutch 6 as in the customary practice.

The hopper drawings `nor the chute which delivers "the cans to the drum l as these are conventional and well understood constructions.

Further lit is to be noted from Figures 2 and 4 1that the usual adjusting fmechanism controlled by the hand wheel 7 is employed forV adjusting the position of the parts Qr cans of dilierent sizes. "The causare removed Ffrom the canningnnaaohine by means has not been shown in the of the usual star wheel "8, as .shown in Figl ure 1. z i

The packer comprises a :shaft A9 mounted below :the body of the machine and connected to the sl-raft 1-0 of the `drum ,l by means of sprocket wheels 11, said sprocket wheels being of the 4same diameterwto insure similar speeds of rotation for theshafts Qcanzd 110,. The Ishaft 9 projects to the rear of rthe machine :and is lcarried ina suitable bracket 12 :adjacent such end. vIt is provided witha fdisk v13 having laora-nk pin 14. .This

15 with 'a :rocking lever 16 ywhose end is car.- ried by means of -a standard 117 'secured to the central :portion of ythe machine, :as :showin in Figures 1 and 2. The outer er ltree-.end

o the ,lever ,116:is guided by means oi' the guiding bracket 18 (see Figure 14.5

A plu-nger, indicated lgenerally :at 1 9, is carried by the lever 1.6 zandhangs downwardly 'o-ver the vring r2. This plunger has its body portion recessed, YLas lindicated at 20, anda pin Q1 is slidably mounted in such recess. rThis pin is prevented from Amoving beyond a predetermined .distance by means of aa slot formed 'therein and 4cooperating witha pin D23 :carried lby 'the body portion of the ;1'. lunger.` TheV rod '21 is provided with a fixed collar 24, and a spring T25 is interposed between the body `portion of `the plunger andthe collar, such vspring having :a predetermined tension adapted yto operate successfully upon theparticular material handled by the banner.. The 1'lower Aend ot the plunger is provided with a head 26 which is socketed and receives the lower end of the rod 2l. This head is adjustable on the rod to accommodate cans of different depths and is locked in position in any suitable manner, as by means of the set screw 27.

From reference to Figure 3, itwill be seen that thef plunger 19is loosely mounted upon the lever 16 and is free to rock thereon. It

carries a set screw28 at its upper end which lits within a recess 29 formed in the shaft 16 to Vthus provide a limit for the lateral.

' spectively, to such lever and to the plunger.

Further, a springl is attached to the plungf er at one end and to an adjusting screw 32 passingthrough the pitman 15 `atthe other end. This yieldingly holds the plunger in position. It isto be noted that they plunger is loosely .mounted upon the y'leverj16 and is adapted toy swing longitudinally and lat-' erally. TheV tension .spring 31 tends'to -hold the plunger in the position shown in Figure 2 although the leverrlvis slanting when it is descending. VThis insures the ,correct registration of the plunger with the` approaching opening and cam. The exact tension of the spring desired to accomplish this result is secured by the adjustmentl of the screw 32. .Y y

j In the conventional types of canners,rit is the usualy practice, as Villustrated in'Figures 5,6 and 7, to provide downturned portions '33 .forming llanges ateach of the apertures in the ring. The material -is fed through these apertures from the hopper carried by the hopper holding bracket 3 (see Figure 1). While thev ring 2 rotates, the shafts 9 and 10 rotate in a uniform manner and the ring is advanced one aperture for each rotation of the drum V1 in the well known manner ofthese conventionalcanners. The sha-ft 9 therefor rotates one time during the advance of onev aperture in the ring 2 and consequently the llever 16 and plunger 119 are reciprocated Vonce `for each aperture..-` The plunger19'(see` Figure 5) isjapproximately 'i'n' line .with the. nearest approaching aperture? andi as iit descends passes in'to.-.1theadvanning'iaprtureg# ab find-.ia

6;'f an i t (ill5 my. 'ea g X Y I bnlclne Hallencourt-@When theeplunger approaches its uppermost limit of travel it pulls out of the cans while the ring 2 rotates at a uniform rate. After the material has been packed, the can passes beneath a head 34C (seefFigure V1) such head being hollow Yand supplied by means cfa brine pipe 35. Thus the cans are .iilled y with brine without any danger of washing of the vegetables out of the cans as 'they .are securelypacked prior to their arrival at the brine filling portion of the machine. Y '1V It will `be seen that a very simple type of packer has been provided. for conventional canning machines, and that this Apacker may be appliedto the machines without altering their construction.

y:It will be A seen' further( that this packerk securely packs' material in the'can. and permits t-he immediate vuse upon the canner of a brinel illing` device without removal of the cans from the canner 'and without danger of washing thexvegetables Vfrom the cans. Thus by means of this invention, the action of the conventional canner may be very much extended. beyondv the mere .filling of cans with the materialg:

It is ltobe understood thatltheterm brine and also therterm vegetables are to be understood as illustrative only and not as limiting terms as used yin the specification and claims of this application. f Y

Although the invention has `been described inV considerable detail,.it`is to be understood that the invention may be variously embodied and is, therefore, to be limited only as claimed. j.: l
